I was seated in a movie, one of high drama, when directly behind me, someone was crunching potato chips, and crumpling the bag to the point where I wanted knock his thick head off..I turned, and it was a woman. I said in a fairly loud voice.."For Chrissake lady, what the hell are you doing? building a nest?" silence for the rest of the show. I believe that rude people dont deserve "friendly" comments. My good friend Dave Mallett (composer of The Garden Song) was doing a show at a local joint. They served food and beer, and the talk was quite loud at one table. Suddenly Dave stopped and said "Why did you pay to come here and talk? You could do that at home for free."
